Hi
I am experiencing some problems when constructing a document piece by
piece. I have boiled downed the problem to the following code:
require 'rubygems'
require 'xml/libxml'
# Envelope XML
xml_string = %{<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
</soapenv:Envelope>}
# Create Document
parser = XML::Parser.string(xml_string, :options =>
XML::Parser::Options::NOBLANKS)
doc = parser.parse
# Add body
envelope_node = doc.find_first("/ns:Envelope",
"ns:http://schemas.xmlsoap.org/soap/envelope/";)
body_node = XML::Node.new("soapenv:Body")
envelope_node << body_node
puts envelope_node.children.size # => 2, the extre node being a node
with content "\n"
# Remove white space in XML string
xml_string.gsub!(/[\n]/, "")
# Create Document with clean string
parser = XML::Parser.string(xml_string, :options =>
XML::Parser::Options::NOBLANKS)
doc = parser.parse
# Add body
envelope_node = doc.find_first("/ns:Envelope",
"ns:http://schemas.xmlsoap.org/soap/envelope/";)
body_node = XML::Node.new("soapenv:Body")
envelope_node << body_node
puts envelope_node.children.size # => 1, the correct Body node
The code first creates an XML::Document from an XML string. It then adds
a Body node to the root Envelope node. The problem is that in the first
example (where the line breaks are kept) results in an extra node being
created. I provided the NOBLANKS option to show that this does not solve
the problem, but the extra node is created whether it is provided or not.
Does anyone have some input on this. I am running the latest 0.9.8
release (great job with it btw).
Kindest regards
Erik
